1Password Chrome Extension seems a bit scary in terms of what it can access?

@FuriousFan

This should help. About 1Password browser permissions

That makes more sense. Would I be notified if 1Password tries to change the permissions it needs in the future or if they grab more data, it would part of what I have to agree to in order to install the extension and I'd never know?

Sorry for the delayed reply @FuriousFan.

If a browser extension changes the required permissions your browser should notify you of the change and ask you to accept these permissions.

I hope this helps to clear things up!
